1 Claim. (C1. 214-7) The present invention relates to new and usefulimprovement in airplanes and more particularly --to a tiltable wingconstruction for the airplane tioning of the wings and motor in a normalmanner for operating the airplane in a forward direction.

A further object is to provide an airplane of this character of simpleand practical construction, which is eficient and-reliable inperformance, relatively inexpensive to manufacture, and otherwis welladapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction andoperation as more fully hereinafter described and claimed, referencesbeing had to the accompanying drawings forming part hereof, wherein likenumerals refer to like parts throughout andin which:

Figure l is a perspective view.

Figure 2 is a fragmentary front elevational' view showing the wings andmotor nacelles in a position for supporting the airplane while at rest.

Figure 3 is a fragmentary top plan view with the fuselage shown insection.

Figure 4 is a fragmentary longitudinal sectional view through thefuselage showing the control means for the tiltable wings, and

Figure 5 is a fragmentary sectional view of the pivotal mounting for oneof the wings and showing the brake mechanism for securing the-wing in adesired adjusted position.

Referring now to the drawings in detail, wherein for the purpose ofillustration I have disclosed a preferred embodiment of the invention.the numeral 5 designates the fuselage of an airplane having a shoulder 6extending horizontally around its nose or front end. I

Secured in the opposite sides of the fuselage is a bearing memberdesignated generally at I having a dense 8 at its outer end and formedwith a recess 9.

A wing W is positioned at each side of the fuselage having its inner endprovided with a socket iii adapted to receive the flanged outer end ofthe bearing 1 and secured in position therein by a retaining ring ii.Positioned in the socket in is a friction disk It adapted for engagementby a similar disk if formed on a backing plate i4 ing plate beingswivelly .secured to a screw is for moving the backing plate and thefriction disk It axially in the recess 9 for engaging the friction diskI 2.

The screw I5 is threaded in the bearing! and is provided with an arm isto which a cable 11 is attached leading to a foot pedal I8 adjacent thepilot's seat is in the fuselage.

'I'hewings W at the opposite sides of the fuselage are connected bymeans of a yoke 20 adapted to conform to the construction of the nose ofthe fuselage and to rest on the shoulder 6 thereof when the wings W arein their normal horizontal position.

The yoke 20 is formed with sockets 2! on the inner edges thereof adaptedto receive spring- Drojected catches 22 mounted in brackets 23 withinthe fuselage to secure the yoke in position on the shoulder 6 and withthe wings in their normal position. The catch 22 is adapted for movementinto retracted position to release the yoke and the wings by means ofcables 24 extending over pulleys 25 in the fuselage and leading to alever 26 pivoted to a suitable support 27 in the pilot's cabin.

3i slidably mounted therein having a foot 32 at rudder and ailerons ofthe usual airplane constructure, the wings will be caused to tiltforwardly into their normal position. The wings may be held in anydesired intermediate position between the vertical and horizontalthrough the use of the frictionelements l2 and I3.

When in normal flight the catches 22 secure the wings against tiltingmovement and when landing the catches are released and through themanipulation of the ailerons the wings may be tilted to adjust the angleof the motors to positioned in the bearing 1, the back of the back- 615permit the plane to be set down vertically.

Iilt believed the details of construction and manner of use of thedevice will be readily understood from the foregoing without furtherdetailed explanation.

Having thus described the invention what I claim is:

An airplane comprising a fuselage, wings pivotally connected to thefuselage for swinging on a horizontal axis laterally with respect to thefuselage, means securing the wings in a desired position, a yokeconnecting the wings for uniform movement, said yoke conforming to thecontour of the front end of the fuselage and adapted to fit thereon whenthe wings are horizontally arranged, and catch means carried by thefuselage releasably engaging the yoke for securing the wings ,with theirsurfaces in a horizontal position.

OSCAR A. SOLOMON.
